How many isomers of 1, 2- dibromobenzene are possible according to Kekule?

Toluene on oxidation gives benzoic acid which on further reaction with NaOH gives the sodium salt of benzoic acid which on further treatment with soda-lime gives benzene. The reaction is shown below: HYDROCARBONS 20 Hence, the correct option is (b). 111. Benzene can be obtained by heating either benzoic acid with X or phenol with Y. X and Y are respectively. (a) zinc dust and soda lime (b) soda lime and zinc dust (c) zinc dust and sodium hydroxide (d) soda lime and copper Benzoic acid on heating with soda lime gives benzene and sodium carbonate. To obtain benzene from phenol, it must be heated
